I agree that the rendering in Firefox is worse than either Opera
or Konqueror (ksvg).  However both Opera and ksvg have at least one
annoying bug that can be seen in the vertical positioning of the expression
inside the integral on the test page.  It should share a baseline with
the integral sign itself but instead it shows up level with the
superscript '=E2=88=9E'. The bug is that if a text chunk
contains positioning information, but the text consists only of=20
spaces ('\040'), then the vertical positioning is ignored.
This leaves the "current position" in the wrong place vertically
for any following text chunks.

Opera also fails to render transparent pattern-fill correctly.
